Jantzen Audio 000-7733 | 0,55 mH | 0,25 Ω | 2% | 16 AWG

The Jantzen Audio 000-7733 Cross Foil Coil represents a premium choice for audiophiles and loudspeaker designers who demand the highest level of crossover performance. This 0.55 mH air core inductor is meticulously engineered to deliver transparent, uncoloured sound reproduction, making it ideal for high-fidelity speaker systems where signal purity is paramount.

This coil excels in passive crossover networks for high-end bookshelf speakers, floor-standing towers, and studio monitors. Its low 0.25 Ω DC resistance ensures minimal power loss and excellent damping factor, while the ±2% tolerance guarantees precise frequency response matching between left and right channels. The 16 AWG copper foil construction is particularly suited for midrange and tweeter circuits where detail retrieval and transient response are critical.

Technically, the Cross Foil design employs a flat copper ribbon wound in a non-inductive pattern to minimise skin effect and proximity losses, resulting in lower distortion compared to conventional round-wire coils. The 57 x 27 mm dimensions allow for compact integration into crossover boards, while the air core eliminates core saturation and hysteresis distortion. Each coil is hand-wound in Denmark to exacting standards, ensuring consistent inductance and resistance values across production batches.

For discerning listeners seeking to elevate their loudspeaker performance, this Jantzen Audio foil coil offers a measurable improvement in clarity and imaging, making it a worthy investment for serious audio projects.
